I agree that ShareWell really does nothing to incentivize Group Hosts, when we seem to be their #1 product.
I think this is a great idea, and possibly scalable to the number of people the host allows (where if a smaller group for some reason needs to get a smaller number of passes, a larger group can still get a larger number of passes). I feel like it could work well within the new membership structure bringing the benefits that you name. Where this may help the site regain some vibrancy, and facilitate the goal of every house that I know, wanting good for sharewell users as individuals and as a community. I started attending your groups prior to the membership changes, and the passion you have for community building and also for being present for people as individuals, was always very clear.
This would be fantastic. They've demotivated the hosts they make their money off of--they need to rethink things in a big way if Sharewell is to continue being what it was meant to be. Otherwise everybody, including them, loses.
